ST. ANDREWS, Scotland -- Throughout this week, we'll update the status of Jordan Spieth becoming the first golfer to ever complete the calendar Grand Slam.
The Good: Does this guy ever have a bad day? Spieth didn't waste any time vaulting to the top of a leader board at a major championship when he shot a front-nine 31 on Thursday. He stalled on the back nine -- most of the field did playing into the wind -- but his opening 67 left him two shots behind playing partner Dustin Johnson. He's now a staggering 28 under par in majors this year, birdieing nearly one third of his holes in nine rounds. After all the talk about Spieth's inexperience on the Old Course, he looked just fine. If Spieth is only going to get more comfortable here, the rest of the field could be in trouble.
Spieth Slam-o-Meter Rating:__ 5.
Eh, probably not. This is Jordan Spieth we're talking about. Let's just say if he and Dustin Johnson played a match in mental toughness, it wouldn't make it to the 18th hole. We're bumping Spieth back up to a 5 because he's right in the mix after Day 1. And like we saw at Chambers Bay, just hanging around the leader board is often the recipe for major success.
